REGISTERXNG ICI] DOOR.

Application filed April 23, 1923.

sage-way, means for registering the openingand closing of the door, and a frame connected with the door which is moved into the path of the next cake of ice, in which po'- sition it is thrown by the cake of ice passing through the door.

ln the accompanying drawings Fig. l is a perspective view; F 1g. 2 is a vertical section .through the door;

Fig. 3 is a similar view showing the frame in another position;

Fig. d is a section on line lv-4 of Fig. 3;

Fig. 5 is a section on line 5 4 of Fig. 2.

The numeral l represents the heavy iron door suspended at the top of the ldoor-way by the hinge 2. This door-way normally rests by gravity in a vertical position as shown in Fig. 2, where it closes the door or passage-way 3. The register 4 is mounted at some convenient point, preferably above the door, and a link 5 loosely connected with the upper end ot the door is pivoted to the lever 6 which operates the register which registers each up and down movement or" the door. An iron frame 7 is rigidly connected by braces 8 with the rear ot' the door as illustrated, and as the door l is swung out by the toi-ward movement of the passing cake ot ice 9, it throws the frame 7 into posi- Serial No. 633,895.

tion to stop the further passage ol the next cake of ice l0, as viewed in Fig. l, and in this way absolutely prevents more than one cake oit icel passing through the door-way at a time.

The Weight of the door l is sufiicient to restore it to its normal position as sho-wn in Fig. 2 by gravity. in outer door ll closes the door-way, and this is mounted on hinges 12 and is provided with any suitable lock.

ln this way a very simple means is pro-v vided for automatically counting each cake ot ice with absolute accuracy, eliminating all possibility ot' more than one cake passing out at a time.

claim:

l. In a. device ot the character described, the combination or'l a frame forming a passageway, a door pivoted at the upper end thereof at a point in the upper portion of the passageway and normally suspended in position to close said passageway, and a frame carried by the door and extending outwardly at an angle therefrom to be moved into said passageway upon the moving ot said door therefrom.

2. In a device ol the character described, the combination of a trame forming a passageway, a door pivoted at the upper end thereof at a point in the upper portion of the passageway, and normally suspended by gravity in a substantially vertical position for closing said passageway, and a frame carried by the door and extending outwardly therefrom at an obtuse angle thereto, in position to be moved into said passageway for obstructing the same upon the moving ot the door therefrom.

In testimony whereof ture.
